The S7OB LCD is a FriendlyElec developed LCD with resistive touch panel. Its resolution is 800 x 480. Its back-light is adjustable via FriendlyElec' s one-wire technology. It works with FriendlyElec's Mini6410, Mini210S, Tiny4412 and NanoPi 2 under Linux, WinCE and Android. Its driver is open source.

The S7OB has a white ABS bezel with mounting holes making it easily deployed in various situations Note: we have a more detailed introduction to the one-wire technology in the appendix.

We observed that for One-Wire Technology on development boards using CPU' s ADC conversion didn't work well, especially for large-size LCDs (7" and larger) with four-wire resistive touch. Some vendors use an external USB or UART module to connect these LCDs. To save CPU' s hardware resources and minimize usage of external modules we developed the one-wire technology which only uses a single GPIO pin and we have integrated this technology in all our LCD controller boards. This technology uses an MCU to communicate with the touch panel' s chip (we use the ADS7843 chip or other chips compatible with ADS7843) and process the four-wire resistor' s ana log signals and output the filtered stable signals to the development board via GPIO. We tested this technology in various LCDs and it worked very well even for a large LCD of 19" and some commonly observed issues such as screen flipping and jittering were not encountered.

Today most LCDs whose size is less than 12" have LED backlight. We use the one-wire' s MCU to process the backlight as well. The backlight is set with a range of values. Users can set a value to the backlight and this value is passed to MCU for processing via one-wire' s GPIO pin. Each FriendlyELEC' s LCD module has a unique ID which is saved in the one-wire' s MCU. When the MCU reads the ID information from GPIO signals it will recognize the LCD model and instruct the bootloader to load the corresponding LCD driver, making a FriendlyELEC LCD plug and play. As for the one-wire technology for our LCDs with capacitive touch we removed the resistive touch panel' s chip but kept the backlight adjusting function and LCD's ID information. Therefore the communication between the capacitive touch and the development board is still standard IIC.


Please note that the one-wire technology is different from the commonly known single-bus communication. Actually in the development board we use a PWM timer (not PWM pins) to generate the communication frequency (9600Hz). For more details please refer to the driver' s source code.
